As a famous Chinese saying goes, "scarce goods are dear", it is precisely because of rarity that they are so precious. In many industries, customization is a successful example of this concept. The customization of logistics products not only requires a certain amount of technology and risk bearing capacity, but also has a large input cost. Therefore, the profit rate is naturally higher than that of conventional products. And the development of enterprises cannot be separated from profits. Therefore, in the engineering machinery parts industry where we are located, customized products have become one of the projects involved in most enterprises' pursuit of profit points. Secondly, customized products can better capture customer resources, provide customers with the matching degree that normal products cannot achieve, and increase customer stickiness. A number of advantages make the customized chemical industry vehicle products competitive.
